7/16" ID over a 1/2" Barb (Is the measurement on the barb ID or OD in this context?) or Compression Fittings. Which has a lesser probability of leaking?

Sorry if this isn't the best place to post...
Barbs come into 1/2 or 3/8 usually. 1/4 is less spread. So, you can't go wrong choosing your barbs.

Some people think compression fittings are the best. You should just take care to respect the size of tube to match your compression fittings.
